Common knowledge on safe use of water, electricity and gas

1. Common sense about the safe use of natural gas

How to use gas safely? People usually refer to flammable gases such as natural gas, liquefied petroleum gas, and coal gas as coal gas.

Gas brings many conveniences to people's lives, but if used improperly, it can also cause disaster. Pay attention to the following points when using gas; 1. Carefully read the operating instructions of gas appliances, etc., and operate and use them in strict accordance with the instructions.

2. When using artificially ignited gas stoves, you must adhere to the principle of "fire waits for gas" when igniting, that is, first bring the fire source close to the stove and then open the gas valve. 3. Always keep gas appliances in good condition, and repair them in time if they find air leakage. If you encounter air leakage during use, you should immediately close the main valve and cut off the gas source.

4. When the gas appliance is in working condition, people cannot leave it for a long time to prevent the fire from being blown out by the wind or extinguished by water overflowing from the pot, causing a large amount of gas leakage and causing a fire. 5. When using gas appliances (such as gas stoves, gas water heaters, etc.), indoor ventilation should be fully ensured to maintain sufficient oxygen to prevent gas poisoning.

2. Common sense about the safe use of gas

1. In the event of an accidental gas leak, do not start any electrical equipment, including turning on lights, exhaust fans, range hoods, televisions, and radios , make phone calls, etc., open doors and windows in time for ventilation, and report to the gas company quickly.

2. Gas appliances must be qualified products from regular manufacturers. Don’t be greedy for temporary gains and create hidden dangers of accidents. 3. When installing a gas water heater, be sure to ask a professional team to perform the installation in a standardized manner. When using the water heater, be sure to maintain good indoor ventilation.

4. When using gas, someone must be in front of the stove to supervise it. Check whether the gas valve is closed before going out and before going to bed every day.

5. During interior decoration, gas facilities cannot be moved, gas meters, gas pipes, etc. must not be installed in cupboards, and gas valves must not be sealed. 6. The gas stove cannot be placed directly below the gas meter. It must be staggered by more than 30 cm directly below the gas meter to prevent the gas meter from being exposed to heat or moisture.

3. How to write safety tips

Water, electricity, and gas are closely related to life. You must pay attention to safety when using them. You should adopt the "two-minute prevention method" (that is, before going to bed and before going out). Take one minute each time to check the water source, air source, fire source and doors and windows in your home to prevent accidents.

The first is water safety: we should keep drinking water clean and sanitary, and do not drink raw or dirty water. The most important thing is to save water, turn off the faucet, and adopt the method of using water for multiple purposes and recycling. Methods to save water; secondly, safety in electricity use, which must be followed: no private pulling or connecting of wires, no staying or playing near electric poles and wires; lastly, safety in gas use: minors are strictly prohibited from using liquefied petroleum gas, and adults are not allowed to use liquefied petroleum gas. When using gas, you should stay nearby until it is used up. After using it, you should turn off the main switch in time. If you encounter a gas leak, you should immediately open the doors and windows to maintain air circulation.

4. What are the common sense for safe use of water heaters?

Be sure to ensure that the power plug and socket match each other, and the contact between the two should be close; if the plug and socket are in loose contact, the plug will heat up. This causes a short circuit in the line.

When installing an electric water heater, the weight of the electric water heater cannot be carried by only two loose bolts. A square steel pipe should also be installed under the electric water heater to ensure that the water heater will not slip off the wall. It must be filled with water before first use and then powered on.

The water in the water tank should be replaced regularly. If it remains for a long time, the water will easily deteriorate. For an electric water heater with an open outlet, it is not allowed to install a valve or any connector other than those specified in the water outlet, because the water outlet (spray) of an electric water heater with an open outlet functions as a vent; if a valve is installed at the outlet or any connector other than those specified is required Joints are equivalent to turning products with open interfaces into closed products, which will affect the service life and cause damage to the machine.

5. Water, electricity and gas safety

The New Year is approaching, and everyone is busy with New Year’s goods or visiting relatives and friends during the holidays. In addition to paying attention to traffic safety, home fire and theft prevention is also a top priority. Most importantly, here are the safety precautions for household water, electricity, and gas during the holidays:

1. Precautions for the use of water pipes:

1. Check whether the faucet has slippery threads , dripping phenomenon,

2. Check whether the water pipe has serious corrosion, such as bulging, severe rust, peeling and thinning.

If there is any of the above phenomena, please ask maintenance personnel to replace it in time. ; Prevent pipes from bursting due to water pressure and preventing water from flooding the mountain when no one is at home.

2. Precautions for using electricity:

1. When using electrical appliances, pay attention to check whether the electrical wires are damaged and whether the sockets are burning, and replace any problematic areas in time. < /p>

2. When going out, try to remove unused electrical appliances from the socket, such as electric mattresses. Long-term use of electricity will cause excessive heat and cause fires.

3. Gas

1. Prevent the water in the appliance from drying out and causing a fire

2. Prevent the water from the appliance from overflowing, causing gas leakage and causing an explosion and fire.

3. Close the valve when going out to prevent fire.

6. How to use gas safely

When using gas, pay attention to ventilation, do not close doors and windows tightly, and do "once on and off three times" (that is, open the kitchen window, After gassing, turn off the stove valve, close the valve in front of the stove, and close the kitchen door).

When using gas, ignite it first and then turn on the gas. If the stove is not lit for a while, turn off the stove switch quickly. Do not deflate the gas first and then ignite it.

Pay attention to adjusting the size of the flame and damper so that the burning flame becomes a blue cone and the flame is stable. When using, people should not stay away to avoid the boiling soup overflowing and extinguishing the flame or the wind blowing out the flame, causing air leakage.

After use, be sure to turn off the gas stove or water heater switch to ensure that no one escapes and the fire is extinguished. At the same time, close the valve in front of the stove to ensure safety.

If not in use for a long time, please close the valve in front of the meter. Keep the kitchen ventilated. Because winter is colder or the air conditioner is turned on in summer, many users tend to close doors and windows. This can easily lead to a large amount of carbon monoxide poisoning due to insufficient gas combustion. Therefore, users should pay attention to maintaining indoor ventilation when using gas.

After using the gas water heater at night, the gas valve must be closed in time to avoid accidents caused by the gas valve opening at night. At the same time, due to the dry climate in winter, which is also a period when fires occur frequently, users should always check whether there are flammable or explosive items piled around natural gas appliances and pipelines.

Do a good job of self-inspection frequently. There are two main methods of self-inspection at home: one is the olfactory inspection method, which means always paying attention to whether there is a strong odor near gas facilities. The gas supply department adds the odorant tetrahydrothiophene to natural gas so that when natural gas leaks, users can smell the odor and prevent accidents.

The second is the brushing liquid inspection method, which is to use a soft-bristled brush dipped in soapy water, washing powder solution and other foaming agents to fully smear all parts of the home such as gas pipeline facilities and gas stoves, and Watch carefully. If bubbles are found, it means there is an air leak.

7. How to use gas water heaters safely

1. The gas water heater must be installed outside the bathroom, and the exhaust pipe must be installed in accordance with national standards so that the exhaust gas generated by the gas water heater can be eliminated during use. Exhaust gas is discharged to the outdoors, and indoor ventilation must be maintained well, otherwise it may cause carbon monoxide poisoning accidents.

2. When using a flue-type gas water heater, it is necessary to ensure natural convection between indoor air and outdoor air. 3. Flue-type gas water heaters need to be used with caution in windy weather conditions.

If you find that wind flows back into the room along the flue, be sure to stop using it. 4. Gas water heaters, especially flue-type gas water heaters, need regular maintenance. Otherwise, due to long-term use, dust and carbon deposits will block the heat exchanger and affect combustion, resulting in a significant increase in carbon monoxide in the flue gas, which may lead to carbon monoxide poisoning accidents.

Therefore, it is necessary to entrust professional maintenance personnel to clean the carbon deposits and dust on the heat exchanger every six months to ensure smooth flue gas emissions.

8. How to protect against electricity and gas

Protection against electricity: 1. Stay away from high-voltage poles, iron towers and lightning rods during thunderstorms.

The lightning rod must be intact and tested regularly. 2. When an electrical equipment failure occurs, do not disassemble it by yourself. Ask an electrician with an electrician's operating certificate to repair it.

When there is a fault with the public electrical equipment or high-voltage lines, call the police and ask the power department to handle it. 3. Construct according to design specifications and operating specifications to ensure installation quality.

Do not use poor quality, worn out and damaged wires and electrical equipment. 4. Electrical equipment must have protective zero connection and protective grounding devices.

And conduct frequent inspections to ensure its safety and reliability. 5. Configure equipment and wires according to the safe current carrying capacity of the line, and do not increase the load arbitrarily to prevent short circuits and leakage caused by overcurrent and heating.

When replacing the line fuse, do not increase the size at will, let alone replace it with other metal wires. 6. When repairing or moving electrical equipment, turn off the power completely and hang a safety sign saying "No closing, someone is working" in a conspicuous position.

Equipment and lines that have not been tested for electricity are considered to be powered. Equipment with capacitors should be discharged first, and movable equipment should be prevented from breaking the wires.

7. Distribution boxes, switchboards, switches, buttons, sockets, wires, etc. that are frequently contacted during use must be intact. If the insulation is aged or damaged, it must be replaced in time.

8. Machine tool work lights and portable temporary lighting must use a safe voltage of no more than 36 volts. Prevent gas: 1. Ventilation method.

When using gas in the kitchen in winter, you must not close all the doors and windows because you are afraid of the cold. The kitchen must be ventilated and refreshed regularly. Generally, the kitchen space is relatively small, so there must be a transom window or a ventilation fan to ensure that fresh air enters and exhaust gas is discharged.

2. Damper adjustment method. When you use various burning appliances, it is best to observe and check the fire point frequently.

Generally, blue flame is normal, and red and yellow flames should not appear. Red and yellow fires are usually produced by incomplete combustion, which not only stimulates gas but also wastes energy.

In addition, families with gas water heaters should try to be careful not to use the water heater continuously for a long time to provide bathing for several people. Because the water heater is a high oxygen consumption burning appliance, it produces a large amount of carbon dioxide after combustion and is not easily discharged indoors quickly. This in turn causes the burning condition of the hot water equipment to decline, and a vicious cycle can easily lead to gas poisoning.

3. Leak detection method. If you feel fishy or stinky smells in the kitchen, feel dizzy or flush, you should first suspect that there is a leak of your own gas or liquefied gas, which may cause mild poisoning.

At this time, be sure to check whether there are leaks in various gas appliances.

9. How to use gas safely

1. What should you pay attention to before using gas? When using gas, you must pay attention to whether there is a smell, confirm that there is no gas leakage before turning on the gas, and pay attention to good ventilation.

2. What should you pay attention to when using gas cylinders? 1. Please pay attention to the inspection period of the cylinder and attach the inspection qualification mark. 2. Please keep the cylinder upright and avoid violent vibrations.

3. Place it in a well-ventilated place away from sunlight. 4. Do not use the cylinder upside down.

5. Do not place objects on the cylinder to avoid ignition. 3. How to check whether the gas pipeline is leaking? When you suspect there is a leak in a gas pipe (pipeline) in your home, do not use a match or lighter to test for leaks. Instead, use soap bubbles to check for leaks.

4. Where is the safest place to install a gas water heater? It should be installed outdoors in a well-ventilated area to avoid accidents of carbon monoxide poisoning. 5. What is the phenomenon of red flames in gas fireworks? What's the danger? How should this be handled? The gas flame is normally light blue. If it is found to be red, it means incomplete combustion.

There is a risk of carbon monoxide poisoning. Please ask a gas professional to repair and adjust the stove immediately. 6. How do you know about a gas leak? 1. Smell - Domestic gas is mixed with odorants, and there will be a self-odor when it leaks.

2. Vision - Gas leakage will cause mist-like white smoke to form in the air. 3. Hearing - there will be a "hissing" sound.

4. Touch - your hand will feel cool when it is close to the leakage hole.

7. How to deal with gas leakage? 1. Turn off the gas switch immediately.

2. Never turn on or off any electrical switch. 3. Gently open all doors and windows and escape outdoors quickly.

4. Call the alarm. 8. Can gas kill people? 1. Gas itself is not toxic, but it has anesthesia and suffocation properties, which reduces biological reaction capabilities.

2. When gas is used improperly, a large amount of carbon monoxide will be produced. Carbon monoxide can easily combine with heme in the blood, causing anoxic state (carbon monoxide poisoning, leading to death). 9. What should you do if carbon monoxide poisoning occurs due to insufficient air when using gas? 1. Turn off the gas switch.

2. Open doors and windows for ventilation. 3. Provide the injured with fresh air.

4. Untie the restraints and clear the respiratory tract. 5. Perform artificial respiration or cardiopulmonary and abdominal compression as needed.

6. Do not turn on or off any power switch until the gas smell has dissipated to avoid sparks and fires. 11. What are the symptoms of carbon monoxide poisoning? 1. Headache, dizziness, nausea and vomiting.

2. There will be a strong sense of collapse, accelerated breathing and pulse, confusion of consciousness, and the inability to move the body on its own. 3. Flushed face, loss of consciousness, respiratory arrest, convulsions, leading to cardiac arrest and death.

12. What should I do if the gas pipeline is accidentally cut due to sewage pipeline construction? If a gas pipeline is accidentally dug due to sewage pipeline construction, citizens are asked to immediately turn off the fire source at home. If a pipeline catches fire, do not put out the fire rashly. Set up a warning line and call the police as soon as possible. Residents near the cut pipeline or pedestrians passing by should avoid it. Smoking, or starting the car or motorcycle engine and various power switches to avoid explosion or burning. Personnel should stay away from the scene as much as possible. Before the handling personnel arrive at the scene, the public is asked to surround the scene with a rope and write a sign saying gas leakage. and other signs to remind passing people and vehicles. .
